Every millimeter of the Retina display was designed, engineered, and built to the most exacting standards. Something that 14.7 million pixels makes exceedingly clear. As does a 1.4 mm thin display panel designed around the human eye — so every interaction feels as natural as can be. It’s that attention to detail that inspired the all-new 21.5‑inch iMac with Retina 4K display. And just like the Retina 5K display, it delivers a larger color palette with more accuracy.

With three-stream 802.11ac technology, iMac takes desktop Wi-Fi to unprecedented speeds. Simply connect to an 802.11ac base station — such as AirPort Extreme or AirPort Time Capsule — and reach data rates of up to 1.3 Gbps.3 That’s triple the previous 802.11n standard. You also get double the channel bandwidth, with 80MHz-wide channels providing more room for more data to flow faster than ever.

Making powerful things simple requires some seriously advanced technologies. OS X is loaded with them. It’s built on a rock-solid, time-tested UNIX foundation that provides unparalleled stability and industry-leading support for Internet standards. OS X takes full advantage of the multicore Intel processors and fast flash storage in your Mac to make quick work of any task. And the incredible graphics capabilities in OS X supply applications like Final Cut Pro with impressive power.

It has an improved scissor mechanism, optimized key travel, and a lower profile that increase control and comfort. And it pairs immediately with your iMac right out of the box.

Magic Mouse 2

The new design of Magic Mouse 2 lets it glide more smoothly across your desk. And since it supports Multi-Touch, you can use simple gestures on its surface to do things such as swipe between web pages and scroll through documents. So if you prefer to use a wireless mouse but want some of the benefits of Multi-Touch, Magic Mouse 2 is a great choice.

Magic Trackpad 2

If you prefer using a trackpad, Magic Trackpad 2 gives you the full range of Multi-Touch gestures and introduces Force Touch to the desktop. Sensors underneath the trackpad surface detect subtle differences in the amount of pressure you apply, bringing more functionality to your fingertips and enabling a deeper connection to your content. This new design, along with a lower profile, makes it even more comfortable to use.
